SOFA AND LOUNGE een.

SPECIFICATION forming part of Letters Patent No. 274,368, dated March 20, 1883.

Application filed February 10, 1833. (No model.)

To all whom it may concern Be it known that I, ROBERT OJPEIRCE, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Sofa and Lounge Beds 5 and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same,

reference being had to the accompanying drawings, and to letters or figures of reference marked thereon ,which form a part of this specitication.

Figure 1 of the drawings is arepresentation of this invention, and shows a perspective view. Fig. 2 is a detail view, and shows the side of the three-part hinge. Fig. 3 is a detail showing the side of the two-part hinge. Fig. 4 is a top view, partly in section, of the threepart hinge.

This invention has relation to devices for supporting the movable back or head-rest of a lounge or sofa bed; and it consists in the construction and novel arrangement of the double-plate or triple-plate hinge, having a spring-catch and registering locking-bearin gs, all as hereinafter set forth, and particularly pointed out in the appended claims.

In the accompanying drawings, the lettcrA designates the framing ot' the body portion of a sofa-bed.

form, being designed to have their breadth at right angles to the parts to which they are secured, in order to give them great strength. The middle plate, G, and the arms G' G are formed with lateral anges a, extending from their attachment edges and perforated for the passage of the fastening-screws. In the construction illustrated, the middle plate, Gr, is

firmly secured to the back bearing or rib, E, the front arm, G, to the bed-support D of the mainframe, and the back arm, Gr, to the movable back B. The arms G' and G'fof the hinges F are connected to the supporting-plate Gr by means of pivots b Zn'. To the back arm, G, is connected a spring-catch, c, the bearin g end d ot' which engages a perforation, e', madein said back arm, near its inner end, eccentric to the main pivot b, which connects said arm to the body-plate Gr. In this body-plate is made a perforatiome', at the same radial distance as the perforation e fron-i the pivot b, and in relative position to register therewith when the back B is in raised position. The spring-catch e then enters the perforation e', locking the arm G' to the middleplate, G, and holding the back in the elevated position.

H indicates a two-part hinge, which serves to connect the head-board O to the hack B. This hinge consists of two plate-arms, K and K', having perforated attachment-flanges f, and pivoted together at g. One of these arms is providedwith a spring-catch, c', engaging a perforation, i1., in the arm, eccentric to the pivot. The other arm 'is also provided with an eccentric perforation, (indicated at h',) which, when the head-board is in raised position, registers with the perforation h and receives the bearing end of the spring-catch, locking the head board in raised position. These hinges are designed to be used in pairs in parallel relation, and the spring-catches of each pair are usually connected by a cord, z, which,
